Key Performance Indicators

The core of the Trendline project are the following eight KPIs:

SpeedPercentage of vehicles travelling within the speed limit
Safety beltPercentage of vehicle occupants using the safety belt or child restraint system correctly
Protective equipmentPercentage of riders of powered two wheelers and bicycles wearing a protective helmet
AlcoholPercentage of drivers driving within the legal limit for blood alcohol content (BAC)
DistractionPercentage of drivers NOT using a handheld mobile device
Vehicle safetyPercentage of new passenger cars with a Euro NCAP safety rating equal or above a predefined threshold
InfrastructurePercentage of distance driven over roads with a safety rating above an agreed threshold
Post-crash careTime elapsed in minutes and seconds between the emergency call following a collision resulting in personal injury and the arrival at the scene of the collision of the emergency services

The 8 KPIs originate from the Commission Staff Working Document 'EU Road Safety Policy Framework 2021-2030 - Next steps towards "Vision Zero" SWD (2019) 283 final.'

In addition, ten new experimental and complementary indicators have been defined within the Trendline project:

  • Driving under the influence of drugs
  • Share of 30km/h road lane lengths in urban zones
  • Red-light negations by road users
  • Compliance with traffic rules at intersections
  • Helmet wearing of PMD riders
  • Self-reported risky behaviour
  • Attitudes towards risky behaviour
  • Use of lights by cyclists in the dark
  • Enforcement of traffic regulations
  • Alternative speeding indicators

For each of these indicators a methodology will be developed and subsequently data collection and analysis will take place at limited scale in order to test the feasibility and reliability of the method.

For each indicator a 'KPI Expert Group' (abbreviated as KEG) is established. The main role of these KEGs is to draft the common methodological guidelines, to give feedback on questions, and to review the report of the KPI which they are covering. Methodological questions in relation to a particular KPI can be directed to the chairperson of the KEG (see below). The KEGs for the eight original KPIs are already operational; KEGs for the new experimental and complementary indicators will be established by July 2023.
